Exchange 2003 OWA 403 Error when accessing Archive Explorer/Search
EV 10.0.3 has been installed. At the moment, it is archiving from Exchange 2003. The OWA Extensions have been published. ISA 2006 rules have been published, and when clicking either Archive Explorer, or Search - an immediate 403 error is displayed. All other functionality works.
All Exchange 2003 server IP's have been entered into ExchangeServers.txt (though as an aside, I have recreated the EVANON VD - and it no longer populates with the IP's, I have had to set it to 'Allow from any client' for now, advice here appreciated).
It is a difficult environment with regard to change control, access to configuration etc - but from what I have seen, ISA appears to be configured correctly. When clicking Archive Explorer - the URL is correctly modified. i.e mail.xxx.com/enterprisevaultproxy
I have explored Symantec Connect,and various threads suggest removing. 'Require Channel SSL' from the Exchange VD on the Exchange servers, this is currently checked. Upon the IIS version on the Exchange Servers, I am assuming the 'Require SSL' check box on newer versions of IIS is the same option upon the EV servers, it is not checked upon any VD. I may be able to test the removal of such, but am wondering if any other potential fixes exist.
Finally, logging into http://exchangeserver/exchange OWA interface allows me to click on either Archive Explorer, or Search - and no 403 error is displayed, however neither is an actual page displayed - just white space.
Everything works from Outlook.
Have had to now leave site, excuse brevity.Suspect may need to get the certificate?
